The first stars of the universe formed in a unique environment, free of metals and ionizing radiation. Current theory and numerical simulations indicate that they may have had an initial mass biased toward very massive stars. Very massive stars still seem to form today, Eta Carina being an example. Although these very massive stars we find today seem to exhibit vast mass loss, like the outbursts of Eta Carina, that might have been different for the first generation of stars. The final fate of a very massive star, whether it explodes as core collapse supernova, as pair instability supernova, as black-hole accretion-driven supernova, as gamma-ray burst, or just collapses to a black hole, depends on how much mass the star has left when it reached the end of its evolution. Additional to initial mass, it also depends on composition, rotation, and stellar companions.
